Sula Dwarf-kingfisher Ceyx wallacii


Justification of Red List Category
This newly-split kingfisher is restricted to a small island group, where it is inferred to have a small population, the majority, but not all, of which forms one subpopulation, and it is in ongoing decline owing to habitat loss and degradation. It is therefore classfied as Near Threatened. If the species is found to rely on primary forest, it may be eligible for listing under a higher threat category.

Population justification
A preliminary population estimate places the global population within the band 2,500-9,999 mature individuals.

Trend justification
The population is suspected to be declining owing to ongoing habitat destruction (del Hoyo et al. 2001).

Distribution and population

Ceyx wallacii is endemic to the Sula islands, Indonesia, where it occurs on the islands of Seho, Taliabu, Mangole and Sanana (del Hoyo et al. 2001).


This species occurs primarily in forested areas, but its level of dependency on primary or other closed forest types is not known.


Rheindt (2010) speculates that all primary forest could have been lost from Taliabu due to the widespread activities of logging companies, with some areas converted to plantations, cultivation and gardens and further conversion to agriculture expected.

Conservation actions

Conservation and research actions underway
No targeted actions are known.

Conservation and research actions proposed
Determine its precise ecological requirements and its ability to persist in degraded and fragmented habitats. Ensure the effective protection of existing protected areas in which it occurs.
